Life Cycle Aware Computing: Reusing Silicon Technology, John Y. Oliver, Rajeevan Amirtharajah, Venkatesh Akella, Roland Geyer, Frederic T. Chong
Life Cycle Aware Computing: Reusing Silicon Technology, John Y. Oliver, Rajeevan Amirtharajah, Venkatesh Akella, Roland Geyer, Frederic T. Chong
Electrical Engineering
Despite the high costs associated with processor manufacturing, the typical chip is used for only a fraction of its expected lifetime. Reusing processors would create a "food chain" of electronic devices that amortizes the energy required to build chips over several computing generations.
Digitally Controlled Zvs Quasi-Resonant Boost Converter With M-Type Switch, Taufik, Patrick Luther, Makbul Anwari
Digitally Controlled Zvs Quasi-Resonant Boost Converter With M-Type Switch, Taufik, Patrick Luther, Makbul Anwari
Electrical Engineering
This paper presents the analysis, modeling and design of zero-voltage-switching (ZVS) quasi resonant boost converter. The use of M-type switch in the topology will be described, including circuitpsilas mode of operation along with the derivations of critical voltage and current equations in each mode. Computer simulation using OrCAD Pspice and hardware development for the resonant converter with digital control will be presented. Results from both simulation and laboratory measurements to compare with theoretical analysis will be discussed.
Strong Guiding Of Light In Hollow Nanowire Structures, Liang Chen, James De Leon, Xiaomin Jin
Strong Guiding Of Light In Hollow Nanowire Structures, Liang Chen, James De Leon, Xiaomin Jin
Electrical Engineering
We have theoretically investigated the guiding mode patterns of hollow nanowires. Two types of nanowires, round shape and hexagonal shape, are examined with different combination of outer and inner radii. Because of electric field discontinuity at hollow interfaces and evanescent modes overlap in low refractive index region, strong light guiding and confinement are achieved in both hollow wire structures.
Interdisciplinary Team Teaching: Lessons For Engineering Instructors From A Capstone Course In Environmental Studies, David Braun, Emmit B. Evans, Randall Knight, Thomas Ruehr
Interdisciplinary Team Teaching: Lessons For Engineering Instructors From A Capstone Course In Environmental Studies, David Braun, Emmit B. Evans, Randall Knight, Thomas Ruehr
Electrical Engineering
The capstone course teaches students to analyze global environmental issues, resources, and human activities with a systems approach based on scientific, economic, political, social and ethical perspectives. Such an intrinsically multifaceted subject demands interdisciplinary treatment. To deliver the interdisciplinary treatment, the course uses diverse faculty teams comprised of faculty from fields in the natural and social sciences, engineering, and business. This work describes the interdisciplinary team teaching strategies adopted for the course and how they evolved with subsequent offerings of the course. We present assessment data measuring how well students achieve course objectives. Finally, experience gleaned from this course for …

Photonics Education Program At California Polytechnic State University, Dennis Derickson, Samuel Agbo, Sean Jobe, John Sharpe, Dan Wasche, Xiaomin Jin
Electrical Engineering
California Polytechnic State University (Cal Poly) has an active photonics-related program. The thrusts of the program are coursework, extensive photonic educational laboratories, an SPIE student branch chapter, and a new Project-Based Learning Institute (PBLI) to promote joint projects with industry.This paper will describe our program for a multidisciplinary approach to photonics education at the undergraduate and master’s degree level.
Teaching And Learning Dc‐Dc Converter Design Using Mathcad, Taufik
Teaching And Learning Dc‐Dc Converter Design Using Mathcad, Taufik
Electrical Engineering
This paper presents an approach for teaching and learning dc-dc converter design using MathCAD. MathCAD provides advantages that greatly improve teaching and learning process especially when long and complicated design equations are involved such as those found in dc-dc converters. A design example using Excel is presented and then compared with the same example using MathCAD. Experience learned from using MathCAD in power electronic courses at Cal Poly will be discussed in this paper.
A Multidisciplinary Design Project In Energy Conversion Electromagnetics Course, Ali Shaban, Ahmad Nafisi, Fred Depiero, Taufik
A Multidisciplinary Design Project In Energy Conversion Electromagnetics Course, Ali Shaban, Ahmad Nafisi, Fred Depiero, Taufik
Electrical Engineering
This paper presents a work-in-progress on a new multidisciplinary design project for an Energy Conversion Electromagnetics course at Cal Poly State University. The project is intended to strengthen the skills of electrical and mechanical engineering students by performing design tasks in a multidisciplinary environment. Concurrently, this new design project is implemented to fulfill ABET criterion 3d. The content and format of the project will be described in this paper. Assessments planned for the project will also be discussed.
